M.S., Engineering Mechanics, Tsinghua University of China, 1997

B.S., Engineering Mechanics, Tsinghua University of China, 1994

Department of Mechanical Engineering, Tsinghua University, worked as Assistant Professor and Associate Professor, 1997-Present, full time

Member of Chinese Aerodynamics Research Society

Member of Chinese Society of Micro-Nano Technology

Microfluidics, experimental fluid mechanics, wetting and interface, superhydrophobic material

Currently Professor Hao is mainly interested in bio-inspired superhydrophobic materials and nano-/microsystems. To be more specific, he studies the wetting, impact, condensation, evaporation and freezing of the droplet on the superhydrophobic surfaces with micro/nano structures, which is of great importance to a wide variety of industrial applications such as anti-icing, self-cleaning and spray cooling.
